Key result
A single lead VDD pacing system maintained >90% AV synchronized pacing in 87% of patients over a mean follow-up of 44 months, with 8.2% requiring reprogramming to VVI mode.
Why the study?
Does a single lead VDD pacing system provide reliable long-term AV synchronized pacing in patients with second- or third-degree AV block?

85 patients (48 males, 37 females, mean age 74 +/- 9 years) with second- or third-degree Mobitz II AV block.

Single-lead VDD pacing may sustain AV synchrony in AV block; leaves open arrhythmia and sensing durability for randomized confirmation.

Does a single lead VDD pacing system provide reliable long-term AV synchronized pacing in patients with second- or third-degree AV block?
Single lead VDD pacing provides reliable long-term AV synchronization with a low rate of complications in patients with advanced AV block.
Folino et al. (1994) conducted a cohort in Second- or third-degree Mobitz II AV block (n=85). Single lead VDD pacing system (Phymos MPS) was evaluated on Maintenance of >90% AV synchronized pacing. A single lead VDD pacing system maintained >90% AV synchronized pacing in 87% of patients over a mean follow-up of 44 months, with 8.2% requiring reprogramming to VVI mode.
